I think not (from what i remember when i was looking at the code earlier today). But it doesn’t matter. The issue with the default state can be fixed with the code i posted above. But maybe there’s a reason why checkbox default state isn’t supported, hope to hear from the OptionTree author.

i used your code tip to can use the “std” to add the defaults values to the checkboxes but the problem now is that you cannot save different values, it keep the “std” value from theme-opion.php file. did that happen and to you?
